We are given that "REASON" is encoded as "TDDQSK". Let's analyze the pattern used for encoding: \[ \begin{array}{|c|c|} \hline \text{Letter} & \text{Code Letter} \\ \hline R & T (\text{Shifted +2}) \\ \hline E & D (\text{Shifted -1}) \\ \hline A & D (\text{Shifted +3}) \\ \hline S & Q (\text{Shifted -2}) \\ \hline O & S (\text{Shifted +4}) \\ \hline N & K (\text{Shifted -3}) \\ \hline \end{array} \] The shifting pattern alternates: +2, -1, +3, -2, +4, -3. Now, applying the same rule to "PRAYER": \[ \begin{array}{|c|c|} \hline \text{Letter} & \text{Code Letter} \\ \hline P & R (\text{Shifted +2}) \\ \hline R & Q (\text{Shifted -1}) \\ \hline A & D (\text{Shifted +3}) \\ \hline Y & W (\text{Shifted -2}) \\ \hline E & I (\text{Shifted +4}) \\ \hline R & O (\text{Shifted -3}) \\ \hline \end{array} \] Thus, "PRAYER" is encoded as "RQDWIO", corresponding to option (b).
"In order to be a teacher, one must graduate from college. All poets are poor. Some Mathematicians are poets. No college graduate is poor."
Which of the following is true?
Five friends A, B, C, D, and E are sitting in a row facing north, but not necessarily in the same order:
B is to the immediate left of C
E is not at any of the ends
D is to the right of E but not next to C
A is at one of the ends
Who is sitting in the middle?
